Covering one of the most important spaces, domes have a magnificent role in Persian mosques. During continuous eras of Islamic architecture masons could promote this techno-spiritual heritage and developed its spatial value. This process reached its apogee in Safavid era. Overshadowing Shia conceptual system carved the cultural context of Safavid society and consequently changed its architectural features. In this context, Safavid illustrious domes acquired modern roles and were dressed differently. In previous studies symbolic meanings of domes have been analyzed mostly in two major groups of “positivist-narrative” and “mystical-hermeneutic” approaches. The followers of traditionalism school by applying mystical-hermeneutic approach have suggested some general meanings for most of dome cases in the entire Islamic world. Manifestation of symbolic meanings such as heaven, paradise, sky and unity is proposed by these scholars. On the other hand, positivist art and architectural historians by utilizing a narrative approach has criticized the traditionalism school. They believe tying any meaning to a traditional architectural element requires achieving clear historical evidences that could be gathered through field studies. Meanwhile there are limited group of scholars that benefit from both hermeneutic and narrative methods. Although they accept the central concept of embodiment of Islamic meanings in the buildings, they provide historical subjective evidences for their arguments. This paper aims to investigate the meaning of Safavid domes by using “Narrative - Hermeneutic” approach. Appropriately, the hypothesis of embodiment of the meaning of a holy tree, called Tuba in Safavid illustrious domes is examined by means of two questions. The first question looks for the original meaning of Tuba in Safavid cultural context which has been studied in a separate paper. That paper indicates that the term Tuba is only mentioned once in the Quran, However its attributes can be ascertained from various hadiths and other relevant references. Additionally, in his The Red Intellect, Sohrevardi describes this tree. Accordingly, Tuba is a divine, tall, with a long shadow tree that is one of the blessings in heaven. The second question is concerned about Tuba’s probable relationships to illustrious Safavid domes. Consequently, to find out the answer characteristics of the two main domes in Madrese Chāhār-bāgh (Soltānī school) and Masjid-i Jamī Abbāsī (Shāh mosque) at Isfahan are analyzed in three spatial scales including the city, the building and the dome chamber. Accordingly, images of the domes in city sky line, dome’s silhouette and shape, outer and inner ornaments as well as the content of dome’s inscriptions are studied. In the urban scale, western traveler’s description as well as studying the city sky line represents a modern picture that forms in the Safavid capital. The picture that displays raised huge domes in the verdure background of the Isfahan as a garden city. In an architectural scale, the projected shape of the dome constructed on a tall drum represents the form of an abstract tree that dominates the mosque and the school and their surrounding area. This image can be better realized by looking to the decorative layer of two domes. Both cases are covered by lavish vegetal decorative patterns drawn on a turquoise background that encompasses the outer and inner shell of the dome. This layer dresses the abstract shape of domes and illustrates an objective tree free standing beyond the city skyline. Moreover, studying the buildings inscriptions may reflect the indicated concepts and intention of their builders and providers. Acordingly inscriptions of main spaces including the entrance (pishtaq), the foyer (hashti), Qibla ivan and minarets were survived. Almost all the inscriptions in both monuments reflect the three main concepts. Inscriptions in both monuments reflect the scientific superiority and spiritual grandeur of Imam Ali. Simultaneously in Madrese Chāhār-bāgh the value of knowledge and in Masjid-i Jamī Abbāsī the importance of congregational mosque are mentioned in different ways. More precisely investigation of dome chamber inscriptions reflects some indicated concepts. Unlikely to the most of dome chambers the applied inscriptions in both cases hardly contain Quranic verses. They mostly include those hadiths and quotes that clarify the role of Imam Ali as the first Imam and also successor and brother of the prophet. More importantly, the mihrab inscription at Madrese Chāhār-bāgh, as the focal element for meaning manifestation in dome chamber, represents the night journey and the ascension of Prophet Muhammad and describes his meeting with the holy tree of Tuba. Finally, qualitative analysis (comparing and content analysis) of the findings evaluated the paper’s hypothesis in three criteria of “logical consistency”, “truthfulness probability” and “completeness”. In the first criterion, the paper indicates on the logical consistency of this hypothesis. Paper findings in the second criterion demonstrate the truthfulness probability for embodiment of the meaning of Tuba. Eventually the last criterion suggests that provided evidences cannot support the completeness of the hypothesis. All in all, this paper suggests that core concept of Tuba tree as the most truthful explanation for the meaning of studies domes.

In the history of architecture, since the architects sought to enter the light inside and as a result, its relationship with external conditions, the concept of transparency has been studied. Therefore, elements such as glass have been used to create transparency and entering the light. But because of lack of technical knowledge to achieve that goal, the less successes have been achieved. By the beginning of Modern architecture in the world, some new words come into the literature of architecture such as the theory of transparency in architecture. Actually transparency is an expression of the thoughts and ideals of Modern architecture in the shape of own self.
 On the other hand, deployment of transparency in the form of glassy architecture, created the base of criticism for its widespread use by critics of modernism. Colin Rowe and Robert Slutsky in the article “The Literal and the phenomenal transparency” presented an integral definition of transparency that could help Postmodern view about transparency. At the first, they classify the Literal transparency as the perceptual or spectacular one, and phenomenal transparency as the conceptual or readable one. Literal transparency actually refers to light permeability of materials and Interference indoor and outdoor spaces. A concept that could be considered as influenced by cubist painting techniques and aesthetics of Modern architecture.
The other statement of transparency, which is often used in the architecture of most of the world, is traction and appeal to create a sequence of spaces inside and outside the building. Which we can see the appearance of a perfect sample of it in Iranian architecture. In Iranian Islamic architecture that the valuable and exalted heritage of our ancients was the concepts of light and its different forms of that in wisdom, philosophy and art, not only before Islam but also after that.
The question is that how was transparency in Iranian Islamic architecture and what are conceptual differences between modern and postmodern architecture with Iranian Islamic architectural transparency. Transparency is among most important architectural issues that are rarely addressed. This importance is because of the comparison of some viewpoints about concept of transparency in the eras of Modern, Post-modern architecture and Iranian Islamic architecture to achieving principles of the formation of the concept and its types with aim to precise definition of structural concepts of objective and subjective.
The Article based on analyzing texts and collected data through librarian search and some documentaries. To narrow the scope of work, the evolution of transparency in the modern and post-modern movement. At first express types of transparency in modern architecture, postmodern and Iran›s Islamic architecture then study Comparative Comparison them and finally, explain and evaluate the transparency of Iran›s Islamic architecture.
This article expresses some kinds of transparency and divides it to Three Categories: Literal transparency, Phenomenal transparency and Semantic transparency and then analyses the philosophical and aesthetic based on architecture of modern, postmodern and Iranian Islamic architects. In this paper, we try to describe the features of transparency by considering of this parameter in modern architecture. After all, transparency in Iranian Islamic architecture is based on the concepts explained. With this method, the use of transparency in each of these eras has been explained and then used in a timeline, and finally examined the evolution of this application.
About achievement of this study to previous examples can be cited to this point what›s that Spatial transparency in the evolution of Iranian architecture introduced by Hadi Mirmiran, which means increased space and reduced material is on properties of Literal transparency more and based on the theory of modernism and is similar to Bruno Zevi,s view.
While results of this study, in addition to the above, in Iranian Islamic architecture, phenomenal transparency and semantic transparency are more and existence of major mental clarity (not objective). In the Iranian Islamic architecture and contrary to the last ones, we can give a hint, that the explanation of Iranian architecture with the modern architecture’s language instead of its Islamic and Iranian language is so wrong. Actually we ignore and connive at some parameters by this viewing. In fact, with dealing like visual material these concepts, a lot of deep cultural concepts in Islamic architecture will be ignored.
